.iMPROVEMEN'i' INIGRAIN MEASURES AND REGISTERS.

Specification-forming part of Letters Patent No. 136,643 dated March 11, 1873.

To all whom it may concern:

Be it known that I, ROYAL B. CLARK, of Lyle, in the county of Mowrer and State of Minnesota, have invented a new and useful Improvement in Grain Measure and Register, of which the following is a specification:

Figure 1 is an end view of my improved device, the cap that covers the register-gearing being removed. Fig.2 is a side view of the same, the cap that covers the register-gearing being shown in section. Fig. 3is a detail vertical section of the same, taken through the line as :10, Fig. 2. Fig. A is a detail view of the lever for emptying the measure.

Similar letters of reference indicate corresponding parts. 1

My invention has for its object to furnish an improved machine for measuring grain and registering the amount as it comes from the separator, and which shall be simple in construction, convenient in use, and reliable in operation; and it consists in the construction and combination of the various parts ofthe machine, as hereinafter more connected a hopper, O, to receive the grain,-

and which should have a glass plate, 0, inserted in its side to enable the attendant to conveniently see when the measure is full. D is a hollow cylinder, made somewhat smaller than and placed within the cylinder A. The

inner cylinder D is pivoted to the cylinder A by a shaft, E, which passes through the centers of the ends of the inner cylinder D, so as to carry the said cylinder with it in its revolution. The shaft E is pivoted to the ends of the outer cylinder A, at such a distance above their centers that the upper side of the inner cylinder maycome close up to the upper side of the outer cylinder A, andconsequently close to the hopper O, leaving a space between the lower sides of the two cylinders to allow the grain to flow out freely through the spout a, the lower side of the outer cylinder being made inclined toward said spout, to facilitate the escape of the grain. The inner cylinder D is divided into two equal parts or compartments by a partition, d ,passing longitudinally through its center, and which is secured to, the shaft E, and to the shell of the said cylinder D. 'On the opposite sides of the cylinder D, upon the. opposite sides of the partition. d are formed openings at, to receive the grain from the hopper O, as shown in Fig. 3. The

cylinder D is designed to be made of such' a size that each of its compartments may contain exactly half a bushel. One end of the shaft E projects and works in a small frame, F, attached to the end of the outer a lever, the end of which rides upon and is pivoted to the shaft K. To the side of the lever L is pivoted a lever-pawl, M, the inner end of which is bent inward, passes through a hole in the lever L, and enters a hole in the wheel J. A number of holes is formed in the wheel J, to receive the end of the pawl M, at such a distance apart that the movement of the wheel J through the space between two of said holes will give a halfrevolution to the inner cylinder D. The outer end of the pawl M is held out from the outer end of the lever L by a small spring, m, attached to one of said parts and pressing against the other. The lever L is held against lateral movement by guards N attached to the end of the cylinder A, and which are provided with stops to limit the throw of the said lever. The teeth of the gear-wheel I of the cylinder-shaft E also mesh into the teeth of the gear-wheel O attached to the shaft 1?, to which shaft is also attached a small gear-wheel, Q, the teethof which mesh into the teeth of the large gearwheel R attached to the shaft S. To the shaft S is also attached a small gear-wheel, T, the teeth of which mesh into the teeth of the; large gear-wheel U attached to the shaft- V. To the shaft V is also attached a small gear-wheel, W, the teeth of which mesh into the teeth of the large gear-wheel X, attached to the inner end of the sleeve Y, through which the said shaft S passes, and which passes through and worksin the frame F. To the outer end of the sleeve Y is attached a finger, Z, and to the end of the shaft S which projects beyond the end of the sleeve Y is attached a finger, A. B is a dial-plate attached to the frame F, and through a hole in the middle part of which the end of the sleeve Y and shaft S passes. Upon the dial plate B are formed two circles of divisionmarks, to the outer one of which the finger A points, and to the inner one of which the finger Z points. The teeth of the gearwheels that operate the shaft S are so ar ranged that the finger A may move one space upon its scale of division-marks at each semi-revolution of the measuring-cylinder, I). 'l'he teeth of the gear-wheels that operate the sleeve Y are so arranged as to move the finger Z through one space upon its circle of division-marks at each revolution of the finger,

to be placed'at the side of a grain thrasher or cleaner so as to receive the grain from an elevator connected with said thrasher or cleaner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with a partitioned cylinder, D (1 d pivoted on shaftE and within a cylinder, A, of the pinion I, gear-wheel J, shaft K, lever L, and spring-pawl M, arranged as and for the purpose described.

ROYAL B. CLARK.
